Abstract

Patente de Invenção: <B>"CATALISADORES DE CIANETO DE METAL DUPLO CRISTALINOS PARA A PREPARAçãO DE POLIéTER-POLIóIS"<D>. A invenção refere-se a catalisadores (DMC) de cianeto de metal duplo substancialmente cristalinos, altamente ativos para a preparação de poliéter-polióis mediante poliadição de óxidos de alquileno com compostos de partida que apresentam átomos de hidrogênio ativos, sendo que o catalisador a) contém compostos de cianeto de metal duplo, b) contém ligantes de complexo orgânico diferentes de c) e c) polímeros funcionalizados. Os catalisadores de acordo com a invenção possuem atividade fortemente aumentada para a preparação do polieterpoliol.Invention Patent: <B> "CRYSTALLINE DOUBLE METAL CYANIDE CATALYSTS FOR THE PREPARATION OF POLYETER-POLYOLS" <D>. The invention relates to substantially crystalline double metal cyanide catalysts (DMC), highly active for the preparation of polyether polyols by polyaddition of alkylene oxides with starting compounds which have active hydrogen atoms, the catalyst being a) contains double metal cyanide compounds, b) contains organic complex binders other than c) and c) functionalized polymers. The catalysts according to the invention have strongly increased activity for the preparation of polyetherpolyol.
